, Beit known that '1, ALBERT W.' M onnrs, acitizen of the United States, and a' resident of.` Camden, New

. Jersey, have'invented certain Improvements in Button-Polish ing Machines, I(being a divisiono an application filed-July 2, 1902,'Serial Noll-1,069)l of which v the following isa specification.

The object of my invention is-toprovide means for buttons orbutton blanks after they have been turned in 'any usual orwell known manner, beforeior v after theyhave been drilled.

' 'The improvements comprising the-polishinigimeans '4 ,forming the subject of my invention 4havebeen applied to a machine constructed in accordance with that shown .'15

Carried by the bd'plate isa 4, on ,which is mounted asliding holder 5 car'- anadjustable post 6 having an adjustable arm 7'- 45'.,

carryingV a. polishing member or'padS. The arm 7-is preferably of spring metal and the holder 5 is lowered 'i by suitable mechanism so as tobrirlg'the polishing member into engagement with'a-button or. button blank;

In lieu ofmounting the polishing member'on such as 7, lmay arrange the post 'y directly over-.the

i blanks in thechuckand mounta spring pressed fin.

" ger in the lower end ofthe same, such finger carrying a suitablev polishing member or? 8, such-arrangement being shown inFig.- 5. All themovin'g'parts of the machine are driven from the main shaft 9,

. to. The housing 10 is arranged directly\in line with' thereby into position to be opershown in my' pending application aboveireferredy-to `Mountedfonjihe bed plate I- o the-machine is a housing 10 having a beveled opening 11, for the reception of the blanks. -'ll'iese,'buttons 'or blanks may be introduced'` y ,bythe operator one at a time .into the opening 11,

ialthough is obvious that the said buttons or'blanks' may be edto the slide piece 12, described hereinafter, in thefmanner described in my patent above referred'.

the' center of the Ichuck 3 and arranged within said ,housing and adapted to be moved back and forth therefin isl -a slide-piece 12, having an aperture 13, which -rests underthe opening ll 'when the slide-piece is'in the'retracted position, and receives from the same one button or blank at a time. This slide is moved foranism and deposits the button or blank directly over 4o'r .within the jaws of the chuck. The slide is shown in plan view in Fig.2, and is beveled at v17 in order that when moving forward with the'button or blank it can push out of the way a button or blank previously. polished-.and ejected by the chuck but not thrownv from lthe bed plate, and it is also provided with a groove`18 on the under side, as shown in Figs.3 and 4, which enables its end to ride over the button or blank yatter the-latter has been seated in the chuck.

The sliding-member is moved from and towards the chuck to feedthe buttons or button blanks thereto, by.- means of a lever 20 carrying a toothed segment 21, which meshes with a rack 22 formed on the top of said sliding member, the housing for the same being cut away or apertured at 23 for the free movement of ysaid toothed segment. This lever 20 is pivoted at 24 and at theoppositeend is connected to a link 25', which linkis attached to a slide arm 26 arranged to move in fixed bearings 27; the movement of said arm being controlled by a cam 28. A spring 29 is connected to a hook 30 at the end of said slide arm and to a lixed member 3l on the -top of the bed'plate. The cam 28 is so formed that Whileit provides a gradual forward movement of the slide to effect the deposit of the button or blank directly over or Within the jaws ofthe chuck, it permits a quick release of the slide arm 26 in order that the spring 29 may effect the return movement of the lever 20 and reset Athe 'sliding member l2 as 'quickly as possible. T his movement is effected 'entirely automatically and the 'sliding member l2 engages a button or blank at each' loperation and moves" the same forward 1towards the chuck. The chuck for holding the buttons or rbutton blanks in position for polishing is supported from beneith the bed plate of the machine and is constantly rotated-duringthe'operation of saidvmachine. This movement necessitates the entrance'ot' said buttons or "wardly at predetermined intervals by suitable mechy invention is shown the accompanying button blanks into the chuck during this rotation, which will -bel effected in, the manner shortly to be described.

'I prefer to employ a chuck constructed and operated in all respects exactly similar to that shown and described in my prior application above referred to, which will have means for closing its jaws against the buttons or button blanks and means for opening said jaws and discharging the buttons or button blanks as soon as the polishing operation hasV been completed. While the sliding member l2 moves the buttons or blanksto a position directly above or adjacent to the open jaws of the chuck, it is necessary that means be provided for positively seating said buttons or blanks within the chuck, and this is accomplished in the following manner: Als I have already said the chuck is constantly revolving as the buttons or button blanks are fed tothe same, and the sliding member for feeding the buttons or blanks to the chuck delivers said buttons or blanks directly over the opening of the latter. The opening is spread, however, due to the fact that the Yclamping means for the chuck are in the lowered or Vinactive position and in order to set said buttons or blanks within the chuck I provide the finger 35, pivoted at 36 to ears 37 carried by the base plate of the machine. The finger 35 is operated by means oi sliding rod 38 secured at 39 to one end of said linger, which rod in turn is moved by a lever controlled by a cam on the main driving shaft 9 of the machine in the same manner as the similar mechanism is operated in my application above referred to. rlhis lever 39 is arranged to lower the setting finger against the button or blank by action of its cam, and this cam then releases the finger, and a spring, suitably mounted and connected, acts quickly to lift the finger from the blank so that the polishing member may be brought into operative position.. As soon therefore as the sliding member has deposited the buttonblanks to the chuck, thev operating meansl has moved the finger 35 so as to press its free end upon lthe button or blank and set it in the jaws of the chuck. The cam is so timed that the finger will be released as soon as the button or blank has been set in the chuck at the same time the clamping device tion with relation thereto and the button or blank will be securelyheld. All this operation takes place during the rapid rotation of the chuck and hence the movement ol' the parts must be quick and accurate.

The polishing mechanism .and its operation is as follows: The movement of the sliding carrier 5 mounted on the standard 4 and having the adjustable post 6 is effected by means of a lever pivoted at 46 to said standard, This lever has a yoked end 47 which engages a pin 48 on the sliding carrier, anda goose-neck 49 at the opposite end having a friction roller 50, which. is engaged by the cam 5l mount-ffl on the main driving shaft 9. This cam effects the v "tical movements ol said holder which are timed so as tagree with the entrance of button blanks in place. iheppost (i carries the arm 7 which maybe of spring nl tal and which has at one end a rouge pad or polishiin member 8. The arm 7 is adjustable in the tool posi, by means of a set screw 53.l Carried by the slide-piece l2 is a rouge cup having a scraper 56, and this cup will be carried forward by the slide-piece as the latter moves the buttons or blanks to the chuck so that on thedownward movement of the post G the pad or polishing member 8 will enter the cup 55 and receive suflicient rouge or other polishing material to :ict upon the buttons or blanks.

As the pad is withdrawn from tho cup, thc lutter rctractcd by the movement of the slide piece l2 and thc excess of material on said pad will bc removed by thc scraper 56, which is carried by a spring arm 57 suit-abi) secured within the cup. As soon as the slide picco withdraws the cup out of the .way oi the pad S, thc operating mechanism causes the latter to descend und cugage a button or blank mounted in the chuck. 'lhe cup 55 as shown herewith is formed integral with thc slide piece l2, but it will be understood that I may make it in a separable piece and secure it to said slide piece 12 without departing from my invention. The movement of the parts carrying the pad 8 is controlled directly by the cam 5l, and said pad is moved into and out of the cup and then onto the blank, the contact oi the latter during its rapid rotation being sufiicicnt to effect the polishing of the same. Instead of having a arm such as 7 for carrying the pad S, the post 6 may bc disposed in line with the center of the chuck and have a central depending linger, spring pressed, and carrying a suitable pad for engagement with the button or blank in the chuck, as lbefore described. Such construction, however, neccssitates certain modiiications in the mechanism for feeding the buttons or blanks and in the means for applying the polishing substance to the pad, all of which, however, is contemplated by my invention. The cams and all the parts of the mechanism are so adjusted that the various steps in the operation of polishing will be carried out without interiercnce of the parts of the mechanism.

Having thus described my invention, I claim and desire to secure by Letters Patent:

1. The combination in a'mucliine for polishing buttons or button blanks, of a rotating chuck for holding the sume, and a exibly mounted polishing pad arranged to be brought into engagement with the button or blank whilev in said chuck.
